Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a safety device for an automobile door opening/closing device which prevents a collision with a motorcycle or the like during the opening operation of an automobile door.

Normally, taxis and other vehicles are equipped with an automatic door opening/closing mechanism that automatically controls the opening/closing of the rear door in order to allow passengers to get on and off smoothly. However, in urban areas where there are a flood of cars and poor road conditions, there are many accidents in which a motorcycle or other vehicle traveling behind the vehicle collides with the rear door that is opened to let a passenger into the vehicle. Since automobiles do not have a means to alert motorcyclists traveling behind them when opening their rear doors, it has not been possible to prevent such collisions.

In view of these drawbacks, the present invention includes an automatic door opening/closing mechanism that opens and closes the doors of an automobile using power as appropriate, and the opening/closing of the automatic door opening/closing mechanism is electrically controlled by an opening/closing switch installed near the driver's seat. A delay circuit that delays the opening command for a predetermined period of time is interposed in the signal path between the opening/closing switch and the automatic door opening/closing mechanism, and a rear warning indicator with a lamp is installed at an appropriate location that can be seen from the rear of the vehicle. An embodiment of the present invention will be described below with reference to the drawings. 1 is the main body of the car, and the rear door 2 is equipped with an automatic door opening/closing mechanism 3. The automatic door opening/closing mechanism 3 has one end pivoted to a pillar and the other end of an operating rod 4. A rod 6a of a cylinder 6 housed inside the door 2 is pivotally connected to the door 2 via a lever 5, so that the actuation of the cylinder 6 causes the door 2 to be opened and closed via the lever 5.The cylinder 6 controls the solenoid valve 7. It is connected to the intake manifold 8 of the engine via a vibe 9.1O111, and the cylinder 6 is operated using the negative pressure of the intake manifold 8.

Note that the automatic door opening/closing mechanism 3 may be of another type, and the power source for opening and closing the door 2 may be a vacuum pump in the case of a diesel vehicle, or the automatic door opening/closing mechanism 3.
If it is an electric type, it is configured to be supplied from a battery.

12 is a door lock mechanism operated by a diaphragm, and a branch pipe 1 is connected to a pipe 9 which is the opening operation side of the door 2.
3, so that the door lock mechanism 12 is unlocked when the door 2 is opened.

Reference numeral 14 denotes an opening/closing switch installed on an instrument panel or the like near the driver's seat, and a control box 15 installed under the passenger's seat or the like provides three types of signals for the door 2: open, closed, and neutral by operating the opening/closing switch 14. The opening/closing switch 14 inputs a signal path 16 instructing the opening of the door 2 to a delay circuit 17 in the control box 15, and connects the output side of the delay circuit 17 to the door 2 in the solenoid valve 7. When the door 2 is opened, the opening command of the open/close switch 14 is transmitted to the electromagnetic valve 7 after a predetermined time delay due to the setting of a timer in the delay circuit 17.

On the other hand, the signal path 18 for commanding the closing of the door 2 in the opening/closing switch 14 is transmitted directly to the solenoid valve 7 without going through the delay circuit 17.
The reference numeral 19 inputted to the closing operation side is a rear warning indicator equipped with a lamp whose lighting is controlled. A flicker circuit has a lighting signal path 20 inputted to the rear warning display 19 in the control box 15, and has text on its surface that calls for appropriate caution such as "Caution when opening/closing the door". 21 to the delay circuit 17, and when the delay circuit 17 is in operation, the rear warning indicator 19 is controlled to blink via the flicker circuit 21.

(22 is a buzzer that is connected in parallel with the rear warning display 19 to the lighting signal path 20 in the control box 15, and is emitted intermittently in synchronization with the rear warning display 19 to alert the driver himself. It is designed to urge caution before opening the door 2.

23 is a courtesy switch installed on the pillar,
The courtesy switch 23 is connected to the delay circuit 17 to detect the position where the door 2 is slightly open, and when such a detection signal is issued, the delay circuit 17 does not operate and the opening signal of the open/close switch 14 is directly transmitted to the solenoid valve 7. When the courtesy switch 23 is switched to open the door 2 from the middle-open position, the delay circuit 17 does not operate and the rear alarm display 19 does not issue an alarm. .

Next, the operation of the safety device in the automobile door opening/closing device according to the present invention will be explained based on the operation chart of FIG.
First, when the open/close switch 14 is operated to the open side, this signal is inputted to the delay circuit 17, and the input to the solenoid valve 7 is suspended for a predetermined period of time due to the action of the delay circuit 17.
An intermittent input signal is sent to the rear warning indicator 19 via the flicker circuit 21, thereby causing the rear warning indicator 19 to
flashes to alert motorcyclists traveling behind that the door 2 is about to be opened, and at the same time, a buzzer 22 installed inside the vehicle intermittently sounds to alert the driver to such conditions. continues for a predetermined period of time (approximately 2 to 3 seconds) and when the action of delay circuit F is completed, the alarm from rear alarm display 19 and buzzer 22 stops, and at the same time a door open signal is sent to solenoid valve 7 to open door 2. When the door 2 is opened, the courtesy switch 23 is switched to the opening side of the door 2.

When the opening/closing switch 14 is operated to the neutral position while the door 2 is being opened, the solenoid valve 7 controls the door 2 to stop at the current open position, and when the door 2 is opened again from the stopped position. Due to the action of the courtesy switch 23, the delay circuit 17 is not activated and the door 2 is opened without any alarm being issued.

In addition, in order to close the door 2 from the open state, by operating the open/close switch 14 to the closing side, the circuit on the closing side does not go through the delay circuit 17, so the door 2 immediately closes. The present invention includes an automatic door opening/closing mechanism 3 that opens and closes the door 2 of an automobile by appropriate power, and the opening/closing of the automatic door opening/closing mechanism 3 is electrically controlled by an opening/closing switch 14 installed near the driver's seat. Since a delay circuit 17 that delays the opening command for a predetermined period of time is interposed in the signal path between the opening/closing switch 14 and the automatic door opening/closing mechanism 3, the door 2 is actually opened when the opening command is operated by the opening/closing switch 14. A predetermined period of time is required for the driver to check the safety at the rear, and the door 2 can be opened immediately by reflexively opening the opening/closing switch 14 when loading a passenger. Therefore, it can contribute to the prevention of unexpected collision accidents of motorcycles etc. against the door 2, and the rear warning indicator 19 by lighting a lamp can be installed at an appropriate place visible from the rear of the car, and the rear warning indicator 19 can be installed. 19 to the delay circuit 17 via the flicker circuit 21
As a result, collisions can be prevented by alerting the driver of the vehicle in front of the vehicle in front of them that the door 2 of the vehicle in front of them will be opened soon and alerting the driver of the vehicle in front of them that the door 2 will be opened soon. Its practical effects, such as being able to prevent accidents from occurring, are enormous.
